Summary
Swelling of tissue due to fluid accumulation, known as oedema, is one of the earliest signs of diseases such as kidney failure, burn injury or lymphedema. All of these are not uncommon conditions. Lymphedema, for example, is a common sequela of radiotherapy or surgery in the treatment of malignancies such as breast, uterine, and prostatic carcinoma. It is reported to occur in up to 40% of patients depending on the type of surgery and whether or not the patient received radiotherapy.

All of these are not uncommon conditions. Lymphedema, for example, is a common sequela of radiotherapy or surgery in the treatment of malignancies such as breast, uterine, and prostatic carcinoma. It is reported to occur in up to 40% of patients depending on the type of surgery and whether or not the patient received radiotherapy. It is estimated that at any time 100000 women are suffering from post- mastectomy lymphedema in Australia alone. Treatment of breast cancer alone therefore, given the incidence of the disease, produces a large at-risk population. Add to this other causes of oedema and the magnitude of the problem becomes clearly apparent. The presence of chronic oedema is often a disfiguring and disabling disorder, usually accompanied by pain, recurrent infection, reduced mobility and impaired function. In acute oedema the problem often resolves with recovery from the underlying pathology. In chronic oedema, progression may be arrested by early intervention including complex physical therapy (exercise regimen, compression bandaging, and massage) which is effective in reducing limb volume, in improving the quality of life, function and body image of patients. Although the assessment of oedema is clearly of clinical importance, relatively few objective and accurate techniques for its measurement exist. Research conducted over the past decade by the applicants has pioneered the Use of Bioelectrical Impedance Analysis for the assessment of lymphedema. This study aims to translate this basic research into clinical practice. Sensitivity and specificity studies will establish normative and threshold values for impedance measurements that can be used as presumptive indicators of oedema. User friendly technology and equipment suitable for clinical use will be developed which should improve treatment therapies.Read moreRead less
Development And Pre-Clinical Evaluation Of A Silicone Dressing For Scar Remediation

Summary
This research is aimed at exploiting advanced polymers as a new therapy for patients with burn related scars, as well as people who are genetically predisposed to scarring due to abnormal healing. In order to progress to clinical trials, the technology needs to be tested on an animal scar model. Successful outcome of these tests will allow the industry partner, Tissue Therapies, to proceed with a clinical trial, paving the way to a therapeutic product available for scar treatment.
Development And Pre-clinical Evaluation Of A Novel Wound Dressing Treatment For Chronic Ulcers

Summary
Chronic leg ulcers are a common, painful and costly reality for many Australians, impacting on sufferers' mobility, social interactions and overall quality of life. This research is directed at developing a novel cost-effective wound dressing for treatment of this condition. This will be achieved through neutralising the ulcer's toxic proteolytic environment through an interactive wound dressing. This then will allow the body's own cells to promote wound healing.

Summary
Breast cancer is the most commonly diagnosed, malignant cancer in women and prostate cancer is the most common non-life style related cancer in men. In spite of the most aggressive therapy, a significant percentage of men and women die of secondary disease (metastases) which usually spreads in the early stages. Currently, therapy is limited to chemotherapy and hormone therapy, both of which show clinical improvement but long term survival is uncertain.

In spite of the most aggressive therapy, a significant percentage of men and women die of secondary disease (metastases) which usually spreads in the early stages. Currently, therapy is limited to chemotherapy and hormone therapy, both of which show clinical improvement but long term survival is uncertain. Targeted alpha therapy (TAT) is a new cancer treatment that we are developing in mouse models of human breast and prostate cancer. With TAT we are exploiting the fact that aggressive breast and prostate cancer cells, but not normal cells, express a particular tissue-barrier degrading protein system (uPA) which is specifically recognised by a natural inhibitor protein (PAI2). This protein inhibitor is labeled with a highly effective cell killing agent, a radioisotope that emits high energy alpha particles with a short range of only a few cell diameters . The alpha-labeled PAI2 selectively kills cancer cells at their most malignant stage by targeting the uPA system on these cells. Another benefit of TAT is that little radiation damage occurs to nearby or distant normal cells. Thus side-effects would be minimised. The outcome of our research to date has been to show the potential of our unique TAT approach as a possible new therapy for breast and prostate cancer. This therapy may well prove beneficial for other cancers. Further safety evaluations studies in mice will be followed by a dose tolerance clinical trial in humans. We expect to be able to show that our TAT will regress breast and prostate cancer tumours without complications in mice. The human trials will show the tolerance limits to TAT. If successful, TAT could provide the basis for a major change in prognosis and quality of life of breast and prostate cancer patients.Read moreRead less
Development Of A Smart Arthroscopy System And Prototype Probe For Joint Tissues

Summary
This project relates to the ever growing use of arthroscopy in the management of joint defects. An innovative probe that will combine all the molecular, microstructural and biomechanical characteristics of joint articular cartialge and bone for the purposes of diagnosis, treatment, treatment-related decisions, comparison of the effectiveness of treament methods and post treatment evaluation will be developed. This system will produce spin-offs for artrhoscopy of other soft tissues and bodies.
